SPECIFICATION forming* part 0f Letters Patent N0. 645,146, dated March 13, 1900.

Application led Tulle l5, 1899. Serial No. 720,717. (No model.)

To all 1071.077?. it may concern:

Be it known that I,- MAURICE C. TRUMBULL, a citizen of the United States, and a resident of Savona, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Culverts, of which the following is a specification.

The object of this invention is to provide a culvert of peculiar construction in which metal plates and beams are employed, being arranged and connected togetherA in such manner as to produce a very strong and durable structure that can be readily put together and will be thoroughly braced in every part.

The invention is more particularly an im provement upon the culvert shown and described in Patent No. 494,576, dated April 4, 1893, and of which patent I am now the sole owner. Y

This invention therefore consists more especially in the particular construction and combination of the parts as hereinafter fully described, and specifically pointed out in the appended claims.

In the accompanying drawings,forming a part hereof, and in which like letters of reference indicate similar parts throughout the several views, Figure l is an end elevation of a culvert constructed in accordance with my invention. Fig. 2 is a side View of the culvert. Fig. 3 is a longitudinal vertical sectional view. Fig. 4 is a transverse sectional view.

Referring to said drawings, A AY designatebody or arch of the culvert is strengthened by the T rails or bars D, curved to extend along the under side of said arch,with its ends abutting upon the upper edges of the iianges b of the angle-beams B, and the arch is further reinforced by longitudinal beams, hereinafter referred to, which extend along the upper side of the body. At the ends of the arch are curved angle-beams E and E', the base-anges e of which are riveted to the end body-plates C, while the upwardly-projecting flanges e serve as a connection for the vertical plates F, forming the end walls of the culvert, the said vertical plates being connected at their upper ends to a horizontal anglebeam G, one at each end of the culvert, the horizontal iianges of said beams projecting inward over the ends of the vertical plates. The vertical plates forming the end walls of the culvert are further connected by 'iiat metal strips H, extending across the front of the wall. I have shown the curved anglebeams E and E with the base-flange projecting outwardly from the end wall at one end of the culvert, as shown by E, and at the other end of the culvert have shown the baseflange extending under the wall and beyond the inner edge of the latter, as shown by E. Either disposition of the said angle-beams could be employed, though the arrangement shown and designated by the letter E is the preferred form. Inboth cases, however, the ends of said angle-beams rest upon the baseflanges of the angle-beams B and arel riveted thereto, as shown. i

Extending along the upper side of the body or arch of the culvert are T-rails, the baseflanges t' resting upon the curved plates C, to

which they are riveted, while the ends of said anges are extended' and bent upward and riveted to the end walls. These T-rails I not only reinforce the body-plates of the arch, but also serve to brace the end walls to each other, and in connection with the T- vrails D, extending transversely across the posed of the Vertical plates F, connected to the angle-beams E and E' and to each other by the flat strips H and angle-beam G, are

IOO

firmly braced by the T-rails I, the end portions may be further braced by the bracketyplates J.

By having the plates C,Which form the body or arch of the culvert, curved in the direction of the arch a very strong structure is presented, and by connecting the said plates to the T-rails D by U-clips d, as shown, the plates are not only tied together, but also iirmly connected to said T-rails. It Will be readily seen, therefore, that I provide a metal culvert in which the construction and arrangement of the parts are such as to form a strong and durable structure with comparativelyflight material and also possesses the important desideratum of presenting a culvert that can be readily and conveniently built, for it Will be understood that the culvert is transported in parts to the place where the culvert is to be located and is built up from the abutments, the dierent parts being made to match and are numbered to facilitate the construction..

Upon the angle-beams at the top of the end Walls of the culvert are secured vertical standards L to support hand-rails Z, and though ordinary gas-pipe may be employed in forming said standards and hand-rails I prefer to use T-rails for the vertical standards, and by extending the side `flanges l and bending the ends of said flanges in opposite directions, as shown, they Will form feet by which they can be riveted to the angle-beams Gr of the culvert and to the top rails Z, While the dat sides ot-the T-rails being toward the roadway over the culvert form a convenient means of connecting an intermediate rail thereto. This construction also provides a stronger hand-rail than is produced by the ordinary gas-pipe, theusual strain upon the standards being offset by the web of the rail in addition to the foot, which extends in the same direction as the Web.

This invention being an improvement upon the construction shown in the patent hereinbefore referred to, I do not therefore claim, broadly, the idea of building a culvert of plates and beams, but by the peculiar construction and arrangement of the parts as herein shown and described I present a structure of this character possessing advantages over culverts of this class.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a culvert of the character described, the combination, of the longitudinal anglebeams B, longitudinally curved plates C forming the body of the arch and resting at vtheir ends on the base-anges of said anglebeams against the flanges thereof, curved rails on the under side of the arch at the j uncture of the body-plates, curved angle-beams at the ends of the arch with their ends resting upon the base-flanges of the longitudinal angle-beams, vertical plates forming the end Walls of the culvert, and tie-rails extending longitudinally along the upper side of the arch and connected to the body-plates and to' the end Walls, the vertical plates of the end Walls being secured to the flanges ofthe curved angle-beams, substantially as shown and described.

2. In a culvert of the character described, the combination, of the longitudinal anglebeams B bolted tothe sill-plates which rest upon the abutment, longitudinally curved plates forming the body of the arch and resting at their ends upon the base-flanges of the an gie-beams againstthe vertical lian ges thereof, curved T-rails on the underside of the arch at the juncture of the body-plates to which they are connected by U-bolts, curved angle-beams upon the ends of the arch With their ends resting upon the base-fiangcs of the longitudinal angle-beams, vertical plates forming the end Walls of the culvert and connected together by a iiat metal strip and by an angle-beam at their upper ends, and T- rails extending along the upper side of the arch and connected to the body-plates by the U-bolts and to the end Walls of the culvert, the parts being constructed and arranged as herein shown and described, and for the purpose set forth.

3. In a culvert of the character described, the combination with the longitudinal anglebeams at the top of the end walls, of the vertical standards or T-rails L having the flanges extended and bent in opposite directions form` ing feet by which they are connected to the angle-beams, a top rail attached to the bent flanges at the upper ends of the standards, and an intermediate rail secured to the flat 'side of said standards, substantially as shown and described.
